Dubbed the 'Penny Black project', it involves making email senders perform a computation taking around 10 seconds, which their recipients can then check for. This delay would limit bulk emailing speeds to around 8000 a day, meaning that to spam all of those 'fresh, guaranteed 25 million addresses' would take approximately 8.5 years." We've reported on this before.
We can found no scientific discipline, nor a healthy profession on the
technical mistakes of the Department of Defense and IBM.
